“I even remember which one it was because I was counting them,” Federer said. “It was one of the swinger wides.

“It’s nice to get past that so I don’t have to think about it ever again, or until the next thousand or so.”

Federer saved all seven break points he faced, while Djokovic lost both break points he faced.

Djokovic sailed a backhand long on break point in the eighth game of the first set.

In the second set, Djokovic had a 40-0 lead in the 11th game, but watched Federer rebound to break his serve with an inside out forehand crosscourt winner.

“The first set belonged to me, but the second set belonged to him more, really,” Federer said. “It was a huge game at 5-all, 40-love for him.

“I crawled my way back into that game and ended up breaking him,” Federer added. “That was big but the break points I saved were even bigger.”

Argentina Open

Rafael Nadal beat Carlos Berlocq 7-6 (7), 6-2, setting up a final against Juan Monaco at the Argentina Open in Buenos Aires.

If he wins today, Nadal will tie Guillermo Vilas for the most clay-court titles with 46.

The top-seeded Nadal was on the brink of losing the first set against the 74th-ranked Berlocq, falling 6-1 to the Argentine in the tiebreak, but the Spaniard won eight of the next nine points to make his first final since winning the Roland Garros title almost nine months.

Monaco, seeking his second title at the Argentina Open, edged Nicolas Almagro of Spain 6-3, 6-7 (6), 6-4 in 2 hours, 28 minutes.

The 60th-ranked Argentine saved 12 of 15 the break points he allowed to Almagro.

Qatar Open

The Czech snapped Azarenka’s 14-match winning streak in Doha and also foiled the Belarusian’s attempt to clinch a record third Qatar Open title.

“It’s an amazing feeling. I’m really excited and. I’ve been working towards this for a long time. I’m happy at the way season has progressed,” said Safarova, who along with Bethanie Mattek-Sands had won their first grand slam doubles titles at the Australian Open last month.

For Azarenka, who was playing her first final since the 2014 Brisbane, where she lost to Serena Williams, it was more heartbreak, in a match in which she committed 21 unforced errors.
